if i am going to perform in situ moisture testing in a slab that is currently covered with vct or any other floor covering for that matter, hasn't the moisture in the slab reached equilibrium, and if so, does it matter what depth the probe is installed? In other words, 40% depth on a slab drying from one side will give you potential equilibrium when the slab is covered, so what about testing a slab that is already covered and has been for some time?
